.This invention; relates to certain new'and useful improvements in sanitary' protector caps for the stems oftobacco pipes, cigar Y holders, etc. The main object is to provide a simple and efficient means designed to prevent-the accumulation on, or admission into,

said Stem, of dust or extraneous-matter when the pipe is carried'in the pocket," or otherwise i v exclude foreign matter. When it isidesired I to clean the i'n'sideof the cap, the entrance end may be pressed againsta hot water faucet,

placed to one side when not in use. i

Fig. 1 isa'side view of my new c l V protector .Fig. is a longitudinalsectionthrough the major aXisof the'cap';

Fig. 3 is a top'plan View;

Fig. 4 is a bottom View; y Fig.5 is a section on the line 5.5 of Fig. 1. fIn general my protective device consists of acap'of a size and design adapted to slide over the end of a pipe stem-or the like, to act as a protecting shield. The cap is molded of rubber or the like, which is sufficiently elastic to adapt itself to pipe stems of different sizes.

I At the entrance end I provide a suitable refit, striction, so that if a pipe stem of smalldimensions is inserted in the body of the Socket this restricted part will properly grip the side of thestem or body, so as to exclude dirt and dust from that end. On the other hand, when a large stem is inserted, the wall of this restricted entrance will'yield sufficiently to ad-' mit it.

Referring to the drawings, 1 represents the main body of my protector cap. 2'is the entrance end, the wall of which is suficiently restricted to fit on the smaller pipe stems or bits. In the preferred construction I form contraction being in the formof aninwardly this restriction by meansof anv inwardly directed flexible or elastic lip 01, flange 3, extending entirely around the opening 2. Directly under the lip or flange 3 andwithin the socket I preferably provide a recess 74,-, back into which the lip 3 will be folded or rolled (see dotted'lines in Fig.2) when a pipe stem V of large size is introduced into the cap. Near-- thereof.

the lower end of the cap I preferably provide opposed notches or corrugations 5-5, to receive theflanges usually provided at the end of a pipe stem to'thereby more securely hold the cap on said stem. 6 is a mere slit, or

such size that when the pipe stem is seated it will not stretch the cap enough to open the slitti. i Y While I have'described'the' preferred embodiment of my invention, it is in my mindthat variousmodifications may be made with- I outdeparture from the spirit and scope What I claim is: 1. As an article of manufacture, a sanitary protector cap for pipe stems and thelike,

consisting of an elastic resilient body open-at one end to receive the Stem of the pipe, the' mouth of said opening being restricted, said restriction being-in the form of an inwardly;

v 2. As an article of manufacture, a sanitary one end to receive the stem of'the pipe, the mouth of said opening being contracted, Said directed elastic flange defining said opening. I

protect-or cap for pipe Stems and the like con- V sisting of an elastic resilient body open at so directed elasticflange around said" opening,

' said body having a flange receiving recess cap directly adjacent to said flange.

7 having a self-closing opening at its opposite end, the mouth of said opening being contracted, and means on the side Wall of the cap adjacent the inner end ofthe pipe stem re-V ceiving cavity, for abutting the flanged end of a pipe stem.

4. As an article of manufacture, a sanitary protector cap for pipe stems and the like, consisting of an elastic resilient body open at one end to receive the stem of a pipe, the opposite end having a self-closing opening therein, With means on the inner side Wall of the cap'adjacent said opposite end for receiving the flanged end of a pipe stem.
